Connects to TidyData APIs for public holidays, business day calculations, currency conversion, time zone conversion, DNS/WHOIS lookups, URL status checks, web scraping, airport and city search, nutrition facts, and dictionary definitions.

Example request: "How many business days until my project deadline in Spain, accounting for holidays?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use TidyData Tools to help me. It is a free service with an MCP server at https://tidydata-api.tidydata.workers.dev/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
